I made Taxana, a crypto tax calculator for Solana Dex traders in Indonesia. It pulls your swap transactions, computes everything with FIFO, calculates PPh Final 0.2% on sells and PPN 0.22% percent on buys, then generates a full PDF report for SPT.
ps: It’s a helper tool, not tax advice, so double check with a tax consultant.

I’ve been building Faktur, a modern invoice management system using Next.js 16, tRPC, Drizzle ORM, and shadcn/ui.
It handles invoices, clients, business profiles, payments, and generates clean PDF invoices.

Introducing Beatcaster, the SaaS web app that helps you share your currently playing Spotify songs on streaming platforms like OBS/Streamlabs! 🎶
I’ve always loved music and wanted an easy way to share what I'm listening to with my community. So I built Beatcaster for people like me, a simple tool to connect Spotify with streaming software without any hassle. It handles the integration, so you can focus on your stream.
As someone who enjoys building full-stack applications, I'm excited to share Beatcaster, a project I designed and built entirely on my own. It runs on Next.js, TypeScript, PostgreSQL, and Tailwind CSS, and I've even self-hosted it on an Ubuntu VPS with Docker and Nginx. You can check it out at beatcaster.fun (http://beatcaster.fun).
